Bundle Description

A till sample survey was completed in the Big Bald Mountain Area of New Brunswick. This area of New Brunswick is located in Northumberland County, northwest of Newcastle which corresponds to NTS map sheet 21-O/1.

The till samples were analysed for 38 trace elements using instrumental neutron activation analysis (INAA) and  x-ray fluorescence (XRF). The samples were irradiated using INAA on a 3 monitor reactor at McMaster University. XRF analysis of the samples was performed by  laboratories at the Institut national de la recherche scientifique (INRS- Géoressources ) in Sainte-Foy, Quebec.  

The geochemical results of this survey were reported by A. Doiron, Geological Survey of Canada, Quebec Office.

The data were published in Geological Survey of Canada Open File 2560.

Analytical Package Description

Laboratory: Institut National de la Recherche Scientifique (INRS-Géoressources), Sainte-Foy, Quebec

Name: INRS XRF + INAA (low detection limits) ( more)

The samples were analysed for 38 trace elements using instrumental neutron activation analysis (INAA) and x-ray fluorescence (XRF).  INAA at low detection limits (calculated at the 3σ level) was performed at McMaster University. Analyses by XRF were performed at the Institut national de la recherche scientifique - Géoressources (INRS) in Sainte-Foy, Quebec
